BOBBIN-TRUCK.

SPECIFICATION forming part of Letters Patent No. 295,441, dated March 18, 1884. Application filed February 1, 1884. (No model.)

To all whom, it may cancer-n5 Be it known that I, WILLIAM E. SHAR- PLES, of Fall River, county of Bristol, State of Massachusetts, have invented an Improvement in Bobbin-Trucks, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to bobbin trucks adapted for use in cotton-mills. Heretofore' it has been common in cotton-mills,when doffing,to use in the gangways lowplatform-trucks containing two or moreboxes set thereon, at least one box being supplied with empty bobbins to be applied to the spindles after the full bobbins are doffed therefrom, the latter being thrown into a so-called yarn-box or full-bobbin box placed on the said truck, the operator pushing or drawing the truck along and removing the full bobbins from the spindles and throwing them into the yarn-box, and taking empty bobbins from the empty-bobbin box and placing them upon the spindles in the place of the full bobbins. When the yarn-box containing the full bobbins has been filled, the truck is pushed or drawn to the spooler-box, and the yarn or full-bobbin box is upturned to dump the full bobbins into said spooler-box. These boxes are never lined, and by throwing bobbins into them frequently become rough or present splinters, and the operators frequently take poor boxes instead of good ones forthe full bobbins, to the great injury of the yarn.

My invention has for its object the construction of a truck especially adapted for use in cotton-mills, whereby the full or yarn bobbins may be more easily and carefully handled when they are to be emptied from the full-bobbin or yarn box into the spooler -box, and whereby the bobbins will not be marred or the yarn injured by contact with the said box.

To this end myinvention consists, primarily,

of a platform-truck provided with one or more boxes firmly fixed thereto, and having an independently movable bottomless full-bobbin receiving or yarn box,consisting of two sides and ends, the lower edges of which are arranged close to the top of the platform of the truck, substantially as will be hereinafter described. I

Figure 1 is a side elevation of my improved truck, Fig. 2, a plan thereof; and Fig. 3, a transverse vertical section on line .70 m, Fig. 1, the dotted lines showing the full-bobbin or yarn box moved to discharge the full bobbins through its open bottom.

The platform A is suitably supported upon the single end wheels, a, and the pair of central wheels, at, in the usual manner. Boxes 6 b, to contain the empty bobbins, are secured to the platform A at its ends, and are provided at the tops of their inner ends with suitable standards, 12 to, which are pivoted, by means of the pivots 2, the ears 0, rigidly connected to the independently-movable bottomless frame or full-bobbin-receiving or yarn box 0, which, as herein shown, is capable of oscillating on the pivots 2. The box 0 consists of two sides and ends, as clearly shown in the drawings,

which are firmly secured together, the bottom edges of the same being preferably of con vexed form, to meet and move over the concaved portion 03 of the platform A, the portion d thus serving as a bottom for the movable box G when in its normal or full-line position, Fig. 3, so that the full bobbins are held therein until it is desired to discharge them into the spooler or other box, when it is only necessary to move, tip, or swing the box 0 upon its pivots, as indicated by the dotted lines in Fig. 3, whereupon the full or yarn bobbins will fall therefrom into the spooler or other box, the top of which is not higher than the platform A. The concaved portion d of the platform A and the interior of the box 0 have a leather or other soft lining, e, to insure smoothness of parts and prevent the injury of bobbins or yarn thrown into and against the interior of the box 0, which is the case with usual unlined boxes when they become rough or uneven.

I claim-- 1. The combination, with a wheeled platform and one or more boxes or compartments, of a movable box, 0, consisting of two sides and ends, and open at bottom and top, and arranged above the said platform with the lower edges of the box in close relation therewith, substantially as and for the purpose specified.

2. The combination, with a wheeled platform and one or more boxes or compartments box being lined, substantially as described, fixed thereon, of a pivoted box or frame, 0, with a soft or yielding lining, as and for the consisting of two sides and ends, the said boX purposes set forth. having its open lower side or bottom edgesin In testimony whereof I have signed my name close relation to the top of the said platform this specification in the presence of two subd, and with its pivotal points above the top scribing Witnesses. edge of said box substantiall as set forth and for the purpose specified. y 7 SHARPLES' 3. The Wheeled platform and the open-bottomed box 0 therein, the upper side of the said platform and the under sides of the said WVitnesses:
